f and also very narrow and thin, wherebytheir handling requires theirbeing" wound into coils. In practice, such strips are usually given apreliminary winding which results in loosely formed (301153.

1 Close and uniform winding and rewindin'g' m of elongated thin stripsof metal, such asbrass and the like, is desirable, among other reasons,toprovide a coil having uniform flush edges in order that damageresultingfroni bending and marrin'g' the edges may be. minimized, andone of the objectsof the invention is the provision of a device forcoiling or rewvinding strips of metal compactly into coils forconvenience and to minimize damage in handling.

Close winding of such-coilsof inet'al is also desirablein order thatthemetal may occupy a minimum amount of space and may be shipped or storedin spaces ofrestricted di'Q mensions and another object i-s to provide adevice adapted to windsheets of metal of the class described'into rollsof as smallvolume as possible whereby the-space occupied in:

storage or shipment is minimized.

The winding, under uniform conditions of.

pullon the sheets, is likewise desirable when.

the sheets are made of uniform sizes. and lengths in order that therolls may be of. the same size and thereby adapted for storage orshipment in containers, and still another ob- 5a: The device is adaptedto be mounted upon ject is to provide a device which is operable avehicle and'moveid from place to place in a factory or plant wherein thecoils are stored after rolling and 'preliminary winding, and

one of the objects of the invention is to pro, vide a device of theclass described, which is capable of' being mounted upon a truck orother vehicle and moved from place to place. The device includes ashaftoperable to rotate a spool about which the coil is wound. The shaft mayalso be utilized as a winding device independently of the spool.

The vehicle is equipped with a platform positioned at a convenientheightfiabove the floorto enable the operators to position the windingspool and metal thereon. The spool isjshown'as standing on end and theloosely wound roll awaiting rewinding as standing on one end. Means areprovided for revolving the spool rapidly after attaching the inner endofthe sheet thereto. By thus standing'the coils on end and rewindingthem upon aspool rapidly revolving abouta verticalaxis, the metal isstretched tightly by reason of the resistance occasioned by its staticinertia. This resistance is augmented by the frictional resistance ofthe lower edges'of the coil in contact with its support. This combinedstatic inertia and frictional resistance is'suili'cient to makeunnecessary the provision of any holding or retarding device in orderthat the metal be wound with the desired degree of compactness, andstill another object is the provisi'on of a winder which is adapted forattaching one end of an elongatec'l-strip of metal thereto for thepurpose of winding the metal into a'compact coil having flush edgeswithout the necessity of anyi retarding or holding devices beingattached to the coil during either the initial or rewinding process. 1

Still another object of'the invention is the provision of a winder ofthe class described, that is compact, strong, and light in weight. Manyother objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from thedisclosure herein given. a

To this endmy invention consists in the novel construction, arrangementand combination of partsv herein .shownland described,

and more particularly pointed out in the claims.

Fig. 7 is a sectional view along the line 7.7 of Fig. 6.

Referring to the drawings, the numeral 10 generally denotes a portabletruck upon which the device is mounted for the purpose of moving thewinder from point to point in a plant as desired. The truck 10 comprisesa bottom frame 18 suitably supported on front and rear axles 14 and 16,respectively. A pair of relatively high wheels 13 support the axle 16.The front axle 14 is pivotally connected to the front end of the truck10 by a mounting 19. Front wheels 15 support the axle 14. The wheels 15are suflicientlv low to move under the frame 18 and enable short turnsof the truck to be made. A tongue 17 provides means for pulling andguiding the truck from place to place.

A pair of transversely extending plates 20 are positioned on the frontend of the truck to support a motor 11. A base plate 21 nositioned onthe rear of the frame 18 provides a mounting for a gear box 22. The gearbox 22 is fastened to the plate 21 by a plurality of bolts 25. Avertically extending frame 33 is mounted on the plate 21. The frame 33includes angle members 23 forming corner posts tied together at theirupper ends by horizontal bars 24 and at their lower ends by angles 27.Rigidity is imparted to the frame 33 by a plurality of diagonallyextending plates 26. The various members comprising the frame 33 arefastened together by rivets 28. A casting or plate 29 is mounted on thetop of the frame 33 and held in position by its downwardly turnedflanged edges. The plate 29 has a downwardly extending annular projection 30 at its mid portion. A collar bearing member 31 is positionedin the annular projection 30 and supported thereon by means of a flange32. j

A vertically extending sleeve is normally supported upon the gear box 22and slidably engages a vertical shaft 37 upon which the sleeve ismounted. The upper end of the shaft 37 terminates substantially flushwith the top face of the plate 29. The lower end of the shaft 37 ispositioned in a vertical recess 39 formed in the gear box 22. A ball 38provides a bearing support for the lower end of the shaft 37.

The upper end of the movable sleeve 36 is normally flush with the topface of the plate 29. A pair of annular flanges 41 on the sleeve 36 areprovided for a urpose hereinafter more particularly descri ed.

A gear 42 positioned in the gear box 22 is mounted on the vertical shaft37. A horizontal shaft 44 provides a mounting for a worm 43 whichoperatively engages the gear 42. A sprocket wheel 45 provides means fordriving the shaft 44. A sprocket wheel 46 is mounted on the motor shaft48. The wheel 46 has a driving connection with the sprocket wheel 45through asprocket chain 47. The motor 11 is connected with a switch box49 by a conduit 50. A flexible conductor 51 is connected at one end withthe switch box 49 and has its other end adapted for connection with anysuitable source of power.

A key 40 provides a splined connection between the sleeve 36 and theshaft 37 on which the sleeve is slidably mounted. The slidable mountingof the sleeve 36 enables it to be moved to the dotted line position ofFig. 4 which position corresponds to the full line position of Fig. 7.For this purpose of manually actuating the sleeve 36 I'have provided alever 52 mounted on a rock shaft 53.

The ends of the shaft 53 are pivotally mounted on pedestal brackets 54.The brackets 54 are supported by a channel member 55 to which thebrackets are connected by a plurality of bolts 56. An arm 57 is fastenedto the central portion of the rock shaft53 so as to be rotatabletherewith. A pair of links 58 pivotally connect the free end of the arm57 with yoke members 59. A rock shaft 60' is mounted at either end inbearing blocks 62. The bearing blocks 62 are fastened to the verticalangles 23 by means of a plurality of bolts 63.' A member 64 is rigidlyconnected to the central portion of the shaft 60. One end of the member64 is fastened to the yoke members 59 by means of a pair of bolts 61,

one of the bolts extending through the upper ends of the link 58 andproviding means pivotally connecting the links with the members 59 and64. A counter weight arm 65 is suitably fastened to the other end of themember 64 and has its outer end turned upwardly to provide a mountingfor a counter weight 66 which is fastened to the arm by a plurality ofbolts 67.

The free end of the yoke members 59 engage the annular flanges 41. onthe sleeve 36. For this purpose each of the members 59 is provided withan inwardly projecting pin 69 each forming a mounting for a roller 68.The rollers 68 are positioned between the flanges 41 and operate torespectively raise and lower the sleeve 36 when the lever 52 is pushedforwardly and rearwardly. The counter weight 66 substantially balancesthe heavy sleeve 36 and enables the sleeve to be manually actuated witha minimum effort.

A two section winding spool 12 is shown in position on the top plate 29.The spool may be constructed of any desired number the plate 29. A keyblock 71 is rigidly mounted in one section of the spool 12 and has aprojection 72 adapted to engage the sleeve 36 when the sleeve is movedto its elevated position by means of the lever 52. A groove 76 formed inthe outer periphery of the sleeve 36 provides a splined connection withthe projection 72 when the sleeve is in its elevated position. A looselywound coil of metal 75 is shown as positioned about the exterior of thespool 12. The strip of metal from which the coil 75 is formed is giventhe preliminary operation of winding merely for convenience in handling.

The end of the strip of metal forming the coil 7 about which the windingof the roll is started may be turned or bent for insertion in either aradial slot 73 or a diagonal slot 74. The insertion of the end of thecoil in either the slot 7 3 or 7 1 insures compactness of the initialwindings. In practice, however, it is found that the rewinding of theroll 75 is satisfactorily accomplished by merely bringing the innerwinding in contact with the exterior periphery of the spool beforestarting the rewinding operation.

The spool 12 having been placed in its operative position and the innerend of the roll 7 5 having been fastened thereto, the operation ofrewinding is as follows: The lever 52 is pushed forwardly to elevate thesleeve to its full line position of Fig. 4. wherein the upper end of thesleeve is in operative engagement with the spool 12, as shown in Fig. 7.

The cable 51 having been connected with a source of electrical energythrough any convenient socket or other connection, the motor is startedby actuating a switch (not shown). The resultant rotation of the shaft37 and the elevated sleeve 36 causes the spool to revolve. The revolvingof the spool with the sleeve 36 very compactly wraps or winds the metalforming the roll 75. The coils thus wound have the further advantage ofoccupying a minimum amount of space for storage or shipment.

Upon completion of the winding operation the spool 12 is contractedsufficiently to remove it from the roll. For this purpose thelongitudinal sections comprising the spool 12 are so constructed as tobe arranged to form a hollow cylinder having a predetermined innordiameter capable of being positioned to align with and "operativelyengage the elevated' sleeve 36." 'When thus arranged, the

longitudinal sections of the spool 12 do not forma complete cylinder buthave a space between two contiguous edges. The opposite longitudinaledges are positioned in contact and permit the sections to revolve as a,unit notwithstanding the space 77. The spool 12 is collapsedsufiiciently for its removal by actuating the bail or handle 70 to movethe spaced apart longitudinal edges of the spool into contact.

The spool 12 is utilized only when coils having a relatively large innerdiameter are to be formed. The coils are made still more compact bydiscarding the spool 12 and utilizing the sleeve 36 as a spool. Theupper end of the sleeve 36 is provided for this purpose with slots ineither of which the end of the coil may be inserted after elevating thesleeve. Upon completion of the winding of the coil, the sleeve isdisengaged from the coil by lowering the sleeve to its dotted lineposition of Fig. 4.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spirit of my invention hence I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. In a device of the kind described driving mechanisnr including arotatable shaft, a

winding spool having an axial bore, means providing a support for thespool in axial alignment with the shaft, a sleeve slidably mounted onthe shaft, and means operable to move the sleeve vertically intooperative engagement with the inner periphery of the spool.
